The common complications of surgery are

Incision infection, postoperative infection, multiple organ failure, etc.

1, incision infection: it is mostly caused by bacterial infection at the incision, which easily leads to incision non-healing, false wound healing, incision cracking, etc.

2. Postoperative infection: Sepsis and bacteremia may be caused by incision infection, respiratory infection and organ infection, which greatly reduces the survival rate of patients.

3. Venous embolism of lower limbs: Most patients stay in bed for a long time after operation, resulting in slow blood circulation and thick blood leading to venous thrombosis of lower limbs. After the thrombus falls off, it may cause pulmonary embolism with the blood moving to the lungs, threatening the life of the patient.
